The Southeastern Pennsylvania Transportation Authority (SEPTA) has reopened its 3,175ft single track bridge, Bridgeport Viaduct, following a four-month $7.6m renovation project.

The 102-year-old bridge carries the Norristown High Speed Line (NHSL) over the Schuylkill River between Bridgeport Station and Norristown Transportation Center (NTC).

The project, which was executed by Railworks Track Systems, allows SEPTA to resume train services between 69th Street Transportation Center and NTC from 11 November.

"We approached this project with an aggressive schedule in order to have as little inconvenience to our passengers as possible."

As part of the project, crews completed bridge timber and tie replacement work, and performed minor structural repairs to the bridge. Activities included replacement of all track ties, bridge timbers, track level walkway and railing system, waterproofing, and structural steel repairs to the NHSL station.

The estimated cost for structural repairs, painting and timber replacement works was about $30m.

SEPTA deputy general manager Jeff Knueppel said: "The bridge ties that sit directly upon the steel structure and hold the rail in place were rotting and failing.

"We approached this project with an aggressive schedule in order to have as little inconvenience to our passengers as possible."

During the renovation project, shuttle buses were operated between NTC and Bridgeport.

Despite completion of designs for timber deck replacement and structural rehabilitation programmes in 2011, SEPTA has deferred major construction to the Viaduct due to loss of capital funding.

In 1985, SEPTA replaced the bridge timbers, rail and power delivery system and repainted the steelwork, while in 2009, it reinforced the bridge piers against scour.
